The attorney for the man accused of murdering Trayvon Martin wants details about a wrongful-death settlement - which could have paid $1 million or more - given to the late teen's parents.

George Zimmerman, who is facing a charge of second-degree murder, has a right to know how much money the homeowners association where he lived and the shooting took place gave Trayvon's parents, his attorney says in a motion filed Thursday.

An attorney for the teen's parents filed the settlement last week, requested it be sealed, and maintains that the agreement is irrelevant to the criminal case against Zimmerman.

He added that Twin Lakes Homeowners Association offered the teen's family more than $1 million but they declined the offer. As a result, it's likely that Trayvon's parents received a more than $1 million settlement, "evidence of a financial interest by certain witnesses," O'Mara said.

Zimmerman, a neighborhood watch volunteer, shot Trayvon, 17, on Feb. 26, 2012, in Retreat VIew Circle, a gated Sanford, Fla. community. Trayvon's family argues the young man was targeted and murdered. Zimmerman says he shot Trayvon in self-defense after being attacked.

Benjamin Crump, an attorney for Trayvon Martin's parents, said the details of the wrongful-death settlement are irrelevant and that O'Mara is simply trying to divert attention away from the facts of the criminal case.

"They are trying to keep the attention off of the night George Zimmerman profiled, pursued, and killed Trayvon Martin," Crump said. "The parents entered into a confidential settlement, with confidential parties for a confidential sum... It has no bearing on the criminal matter."

O'Mara argues however that Trayvon's father, Tracy Martin, and mother, Sybrina Fulton, could be biased witnesses as a result of the money they have received.

In his motion, O'Mara points to a police statement that says Tracy Martin originally denied that a voice heard screaming for help on a 911 call the night of the shooting was that of his son, then later changed his story.

Crump contended Thursday that voice experts will be able to deal with such issues and that neither parents were present during the most important part of the night, the shooting.

"All entities involved decided it would be best if this matter was confidential," he reiterated of the settlement.

Meanwhile, O'Mara says he has not received a copy of the agreement and wants the court to unseal it.
